Hi Takeshi,
I have now installed the setup environment on Ubuntu 16.04. I am still
getting the same problem.
I observed the following:
1) If i run: *sudo ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file ryu/services/protocols/bgp/bgp_sample_conf.py *
inside the namespace i.e using *mininet/util/m r1*
i am getting the error: *Error creating socket: [Errno 98] Address
already in use*
The error comes even if i stop quagga using: *sudo /etc/init.d/quagga
stop*
2) If i try to kill quagga using: *sudo killall quagga* i get the
following error message.
* --quagga: no process found*
3) If i run: *sudo ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file ryu/services/protocols/bgp/bgp_sample_conf.py *
directly inside a terminal *without using mininet/util/m r1*
the application works fine without any error.
Pls advice how to resolve the problem.
Thanks
Hadem
